International Comparison of Walkability Evaluation using Virtual Reality

International Symposium on Ubiquitous Virtual Reality 2009

M obile phones are now ubiquitous—recent advances in mobile phone platforms have given them many new user-friendly capabilities, such as taking pictures with a built-in camera, finding locations through GPS, playing audio/video files, rendering hardware-accelerated 3D graphics, and browsing the Internet. These features with augmented reality (AR) technologies also make mobile phones an ideal us...

hazard evaluation of gas condensate stabilization and dehydration unit of parsian gas refinery using hazop procedures

شناسایی مخاطرات در واحد 400 پالایشگاه گاز پارسیان. در این پروزه با بکارگیری از تکنیک hazop به شناسا یی مخاطرات ، انحرافات ممکن و در صورت لزوم ارایه راهکارهای مناسب جهت افزایش ایمنی فرا یند پرداخته میگردد. شرایط عملیاتی مخاطره آمیز نظیر فشار و دمای بالا و وجود ترکیبات مختلف سمی و قابل انفجار در واحدهای پالایش گاز، ضرورت توجه به موارد ایمنی در این چنین واحدهایی را مشخص می سازد. مطالعه hazop یک ر...

A Comparison of Virtual Reality Platforms

Investigating the Educational Capabilities of Virtual Reality Technology Based on the Evaluation of Visual Perception Components

Since virtual reality technology is increasingly and widely used in various fields, and in particular education, it is necessary to examine the audience’s perception obtained using this technology in order to study its instructional capabilities. So, the present study aims to investigate the instructional capabilities of the virtual reality system using a comparative analysis of environmental p...

DIVE A multi-user virtual reality system - Virtual Reality Annual International Symposium, 1993., 1993 IEEE

The Distributed Interactive Virtual Environment (DIVE) is a heterogeneous distributed VR system based on UNIX and Internet networking protocols. Each participating process has a copy of a replicated database and changes are propagated to the other processes with reliable multicast protocols. DIVE provides a dynamic virtual environment whew applications and users can enter and leave the environm...
